4 Claims.

This invention relates to refrigerating apparatus and particularlyto thearrangement of a refrigerating element in a refrigerator cabinet.

One of the objects ofthis invention is to provide an improvedarrangement of a refrigerating element in a refrigerator cabinet.

A further object of this invention is to arrange a refrigerating elementwithin a refrigerator cabinet in such a manner so that the refrigerantcontrol valves and operating mechanism thereof may be accessible fromthe exterior of said cabinet. v

A further object is to arrange a refrigerating element within arefrigerator cabinet in such a manner so that the refrigerant valve andoperating mechanism thereof are accessible from the exterior of saidcabinet, and to arrange said cabinet in such a manner so that said valveand operating mechanism are accessible from the ex- 0 terior of the roomor apartment in which said cabinet is located.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accom- 25panying drawings, wherein a preferred form of the present invention isclearly shown.

In the drawings:

Fig. l is a vertical cross sectional view of a refrigerator cabinetshowing the refrigerating 30 element and showing features embodying thepresent invention;

Fig. 2 is a view of a portion of the apparatus shown in Fig. 1 taken inthe direction of the arrow 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 2 and showing the closure means for theopening provided in the rear of the cabinet in an open position;

Fig. 4 is a view in cross section of a portion of the refrigeratingelement forming a part of. the 40 present invention; and

Fig. 5 is a front view in elevation of the apparatus shown in Fig. 4.

Referring to the drawings the numeral designates a refrigerator cabinetprovided with a 45 'cooling compartment 21 formed by an inner lining 23.The cabinet also includes suitable insulation 25 disposed between theinner lining 23 and an outer covering 27. A refrigerating ele- 50 mentis disposed within the cooling compartment 21. element may be used forsupplying refrigerant to the refrigerating element 30 and for instance arefrigerant circulating element of the type dis- 55 closed in the patentto Harry 3. Hull No. 1,648,-

Any suitable refrigerant circulating 178 issued November 8, 1927. Thecabinet also includes the usual opening 38 closed by door 40.

Referring more in detail to the drawings, the refrigerating element 30may be suspended within the cooling compartment 21 in any suitablemanner, and for instance, may be clamped to the inner lining 23 alongthe rear wall thereof by screws and may be supported at the opposite endof said refrigerating element by means 46. The refrigerating elementillustrated includes a container 48 adapted to contain a quantity ofliquid refrigerant and includes means in the form .of ducts 50 forming afreezing compartment adapted to receive a plurality of ice makingreceptacles 53. The container 40 is provided with an end ring which isclamped to the inner lining 23 by an outer ring'57 and the screws 45.Thus the end ring 55 will engage the inner lining 23 on the inner sidethereof while the ring 57 will engage the lining 23 of the opposite sidethereof while the screws 45 will clamp the ring 55 and 5'7 to saidlining to thus support the valve plate end of the refrigerating elementto the inner lining 23.

The refrigerating'element 30 is provided with the usual valve plate 60which is rigidly clamped to the end ring 55 by means of bolts 63. Thevalve plate 60 is adapted to support the usual float valve mechanismwithin said container which is removable from said refrigerating elementby the removal of the valve plate 60 which may be accomplished byremoval of the bolts 63. The valve plate is provided with refrigerantvalve connections and 71 on the outer side thereof. The connections 70provides a connection for a vapor conduit 74 and the connection 71provides a connection for liquid refrigerant conduit 75. The refrigerantvalve connections 70 and 71 are provided with shut ofi valves not shownherein but clearly shown and described in the copending application ofOtto M. Summers, Serial No. 266,397 filed March 31, 1928.

The refrigerantconduits 74 and 75 may be received by an opening providedin a wall 82 formed by the room or apartment in which the refrigeratorcabinet 20 is located, the conduits leading to the refrigerantcirculating element.

According to this invention the refrigerating element 30 is disposed onone side of the lining 23 while the valve plate 60 is accessible fromthe opposite side thereof. Thus the valve plate 50 extends through anopening formed by the inner lining 23 and terminates between the lining23 and the outer covering 27. The outer cabinet 20 is located, repairsof the refrigerant 1 covering 27 is provided with an opening 93 adjacentthe valve plate 60, which opening is provided with swinging closuremeans 94. Suitableinsulation 95 such as kapok may be inserted 70 and 71.

From the foregoing description it will be noted that there is provided arefrigerating element. disposed within a refrigerator cabinet in such amanner that the refrigerant valves and operating mechanism therefor areaccessible from the complished without entering the. apartment in whichthe refrigeratorcabinet is located. In order to do this all that isnecessary is to pump the refrigerant from the container 48 then removethe conduits from the valve connections. After the'conduits are removed,the valve plate 60 together with the float valve mechanism may beremoved, by removing the screws 63, the plate and float then may bewithdrawn from the cabinet 20 through opening 93 provided in the rear ofthe cabinet and through opening 80 provided in the wall 82 which opening80 may be normally closed by door 99. Also this arrangement isadvantageous should there be a leak between the valve plate 60 and ringin which case the gas formed by the liquid refrigerant in the container48 would not escape-into the cooling compartment 21 which would beundesirable. Since the refrigerant circulating element is disposed.

in the basement or any other room or apartment from the'room orapartment in which the circulating element may be made without enteringthe apartment in which the cabinet 20 is located.

While the form of embodiment of the invention as herein disclosed,constitutes a preferred form, it. is to be understood that other forms Imight be adopted, all coming within the scope of the claims whichfollow.
